That bar is just for editing the row style. I can't even highlight the text to click on the box to edit it. This happens even on my wide pc monitor .
I'm attaching the screenshot that shows I can select the text just above the block of text.

You probably have an element below that area with a big negative top margin which can make it overlap too much. Try adjusting the margins for the elements above and below that one.
Also, it would be better to use a computer for this.
